Exemption for refinery waste applies to sludge oil from crude coconut oil refining when it is an incidental residue, not a distinct product.

Sludge oil (soap stock) generated during the refining of crude coconut oil was treated as an incidental residue of manufacture, not as a distinct excisable product. The decisive factor was its character as waste arising inevitably in the refining process, rather than any sale value it might fetch. On that basis, the exemption under Notification No. 89/95-CE was held applicable, and the duty demand could not be sustained.

Issues: Whether sludge oil (soap stock) arising in the course of refining crude coconut oil is eligible for exemption under Notification No. 89/95-CE dated 18.09.1995.

Analysis: The same question had already been decided in the context of similar refining processes, where incidental remnants or unwanted materials emerging during manufacture were treated as waste rather than manufactured excisable goods. The determining factor was held to be the character of the product as an inevitable residue of refining, not the sale value it may fetch. Applying that approach, sludge oil generated during the refining of crude coconut oil was treated as waste arising in the course of manufacture and not as a distinct dutiable product. On that basis, the exemption notification was held applicable.

Conclusion: The sludge oil was eligible for exemption and the duty demand could not be sustained.

Ratio Decidendi: Incidental residue or waste arising during the refining process, when not manufactured as a distinct product, is eligible for exemption under the relevant notification notwithstanding any sale value it may command.
